Glad to hear you got it working!

The Set Point URL you have configured seems a little odd to me. The set point url is where to reach out to with a message if one of the HTTP points is set. So, if you have it pointed at the local httpds, you may be setting those values into other HTTP (or the same) point. Not sure what the objective is.

Certainly! Sorry you were inconvenienced by the queuing issue!

Alas the documentation is scattered around the forum primarily, although the context help (blue ? next to the data source name on the edit page) is useful. Virtual points are perhaps the simplest of points. You can disable polling on the data source, and then they're just points to set values into. The data source can also poll to make the points do simple things like increment, generate random values, alternate, or whatever is sensible to the data type.

Meta points are event-driven timer-driven script bodies that are an iceberg of features with limitless use cases somewhat described here: https://github.com/infiniteautomation/ma-core-public/blob/main/Core/web/WEB-INF/dox/mangoJavaScript.htm

I have posted a great many examples of meta points and scripts around the forum.

they have worked until we put a new instance of Mango in

I'm not aware of any changes in the Modbus4J code in quite some time. Certainly none at the protocol level.

Will do, thanks Phil. I don't know much about that bus as I'm, of course, coming in well after the fact. I thought it very strange that there are echos as well, was going to ask if that's something you expect to see in those logs. I shouldn't be seeing that at all

You can access them two ways,

<#list mapped.p123.vo.tags?keys as tagKey> ${tagKey} - ${mapped.p123.vo.tags[tagKey]} </#list> <br/> ${mapped.p123.tags}

The first is iterating over the keys in the map of tags for the point with key "p123" (specified in the report configuration) while the second is a string with the tags joined by a ", ", and paired by a ": "

perfect thanks Phil :)

So I think the live point values fixed itself on the restart and the last post was in error because I was looking at cached values and not realizing this. it appears to be working perfect again now! I made changes to the data source names on Friday before this live value issue began happening and thought it might have been related. This is a production server so we don't like to restart but I guess a restart is required sometimes because it's working correctly now.

Yes, that is true. So, you would want to update the tag in the existing tags map, then, like,

var tags = com.serotonin.m2m2.db.dao.DataPointTagsDao.instance.getTagsForDataPointId( p.getDataPointWrapper().getId() ); tags.key = "value"; CONTEXT_POINTS.p.getVO().setTags(tags); com.serotonin.m2m2.db.dao.DataPointDao.instance.saveDataPoint(CONTEXT_POINTS.p.getVO());

There are not methods to update a tag individually of the other tags. The DataPointTagsDao takes the whole DataPointVO as its argument.

To shrink the H2 database? No, you don't need to touch the NoSQL database. The steps of,

Purge tables that need purging Run an SQL backup Stop Mango Move you Mango/databases/mah2.h2.db file (to keep a backup) Start Mango Restore the SQL backup from step 2

Will shrink the H2 database, as you have found.

@phillip-weeks Great, glad you got it working. The change I mentioned above will still be making its way into 3.4 so it should be easier next time.

OK Thank-you

Synchronize history prior to is set at 1 minute.

I've taken a representative sample of points, and checked again today. It looks like all points are affected.

Here's the data again as of today, but with a lot more points.. Well if we cannot resolve this by May 3, it will be purged from the source. It's not the end of the world, but if you are interested in investigating it, it might help you find issues. I don't know if this is a problem on our end either.

Still at source:

I want the expression to run a few seconds after a button is clicked, I need to wait for a script outside of mango to run. So I don't have a callback. The script replaces an image in the file store. Once it done I want to change a pointless parameter like Phil did above

@craigweb Not currently possible on the watchlist itself. If you mean in a <ma-serial-chart> on a custom page you should be able to set the options attribute according to the amcharts documentation.

@CraigWeb problem solved i hope that this could help you.

<button onclick="goBack()">Go Back</button> <script> function goBack() { window.history.back(); } </script>

Hi glamprecht,

The solution is likely similar to the self-refreshing image solution here: https://forum.infiniteautomation.com/topic/3428/img-refresh

Simply modify some variable that is in the ng-src of the image as a parameter and it should re-request the image without having to reload the whole page.

Yes, you could use the USB utility to move the whole update bundle zip into your /opt/mango directory if named as I suggested previously.

It looks like your DNS resolved the correct IP, but you didn't (or couldn't) get a response. You could try https://store.infiniteautomation.com instead of http:// as your store.url in your env.properties file.

Hi Wingnut2.0,

I made an argument for it when this came up, but the pushback of "You can request those points, then compile a request for the values from them," was strong. If you can expand on the value of having it in a simple single request, you may find more traction for it than I did. That's why I just supplied the code here.

Hi pierjsap,

The ASCII file reader uses regex to parse values by line of the input.

There is good information in context help for the data file data source as to how to use it. That's the blue question mark by the data source name while you are editing it.

In brief, you have to implement a Java class that extends the abstract importer you wish to use. These threads have examples:
https://forum.infiniteautomation.com/topic/1636/problem-with-defining-class-for-csv-datafile-import
https://forum.infiniteautomation.com/topic/3126/file-datasource-breaks-on-file-upload

We can work through the CSV you need to import in this thread, if you'd like.

Another option that has come up in the past is reading the CSV from a scripting data source, as in this thread: https://forum.infiniteautomation.com/topic/2970/is-it-possible-to-read-several-csv-documents-by-scripting
